About

11.2 µm - IR Longwave Window Band - 2 km resolution - the traditional longwave infrared window band, is used to diagnose discrete clouds and organized features for general weather forecasting, analysis, and broadcasting applications. Observations from this IR window channel characterize atmospheric processes associated with extratropical cyclones and also in single thunderstorms and convective complexes.

*GOES-17 Infrared Image Quality

During post-launch testing of the GOES-17 ABI instrument, an issue with the instrument's cooling system was discovered. The loop heat pipe (LHP) subsystem, which transfers heat from the ABI electronics to the radiator, is not operating at its designed capacity. The consequence of this is that the ABI detectors cannot be maintained at their intended temperatures under certain orbital conditions. This is preventing adequate cooling for some of the infrared (IR) channels on the instrument during parts of the night, leading to partial loss of ABI imagery. Learn more.
